## Description

One puzzle a day, the same for the whole world. Miss it and the archive is right there.

One of these tiles is not the same color. Can you see which?

Keenly is a daily test of perception. Every day the whole world gets the same
puzzle: a grid of color tiles where exactly one is a slightly different shade.
Seven rounds, and the difference shrinks every time — down to the edge of human
vision (ΔE 1.2, near the just-noticeable-difference).

One mistake ends the run — that is what makes each find worth something. But a
lost run no longer costs you the day: every past puzzle is one tap away in the
archive.

WHAT YOU ACTUALLY LEARN
Not an invented percentile — your own data. The finest difference you have ever
resolved, your clear rate at each step of the ladder, and the exact point where
your eye starts to lose the thread.

• One run a day — the same puzzle worldwide
• 7 rounds, sudden death, scored on how deep you get and how fast
• An archive of every past puzzle — replays never touch your streak
• Daily streak with a freeze, so one busy day doesn't erase a month
• A shareable result card — spoiler-free, never shows a color
• Color-blind (CVD) mode — leans on lightness, and the answer stays in the same
  place for every player, so the test is identical for everyone
• Quiet editorial design. No clutter, no candy.

Keenly+ unlocks Hard & Master practice, four color themes (including dark),
full history, and removes all ads — one payment, forever.
